To all whom t may Concern:

Be 1t known that l, MLILADORE citizen of the -United- States7 residing at Lamar, in the county of Barton and State- This invention relates to certain improvements in circuit closers and has relation more particularly to a device of this gen# eral characterV especially designed and adapted for use in connection wit; low tension dual i' ition for motors or the like" and an object of the invention is to provide a device .of this general character having novel and improved means whereby the operation thereof by unauthorized persons is e'ectually guarded against.

Furthermore, it is an object of the invention to provide a device of this general character adapted to 'be inclosed within a casing and having means of a novel and improved character, whereby access within.

L the casing is prevented during the' period the closer is adjusted into open or break position. l

The invention consists'in the details of construction and in the combination and arrangement of the several parts of my irnproved circuit closer whereby certain important advantages are attained and thedevice is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more 'fully set forth. A I

The novel features of the invention will be v carefully deiined in the appended claims.

dii

i ln order that my invention may be the better understood, l will. now proceed to describe the same with reference to the ac-k companying drawings, wherein- Figure l is a sectional view taken through a circuit closer constructed in accordance with an embodiment or" my invention; Fig.

2 is a top plan view of the device as herein embodied; Fig. 3 is a view, partly in bottom plan, with the base oi'- the casing removed, togetherwith the contacts coacting therewith; Fig, i is a view in top plan ci" the base portion of the casing illustrating the contacts; Fig. 5 is a fragmentary tea turc, partly in elevation, and partly in sec ytion, illustrating in detail views the per-A mutation mechanism herein included;

A, Bur'roiv,

6 is a view partly iny elevation and partly in sectionlof the lever or vpawl herein ineluded; F ig. 7 is a view in plan of .an eX- pansible member herein embodied; and employed in vconnection with the permutation mechanism; Fig. 8 is a view in top plan of aslightly modified form of the invention.

As disclosed in the accompanying drawings, l denotes a cylindrical casing having one face open, said open face being adapted Patented new. s, rois'.

to be closed by the cover member 2 provided ywith an annular liange adapted to overlie the 'periphery ofthe casing and detachably engage said casing through the me dium of conventional, threads. At substantially its axial center, the cover 2- is provided with the sleeve 3 adapted to be disposed within the casing l to a predetermined extent and in which is rotatably mountedk the spindle eladapted'to' project exteriorly of the casing when in applied position and to such projeetediportion of the spindle is suitably aiiixed an operating knob 5 whereby requisite axial rotation may be imparted to the spindle 4, the knob 5 is provided with the annular dial plate 6 adapted to move therewith and provided with the graduations 7 coacting with suitable demarcations 8, `for a purpose which will hereinafter be seltevident lt is to be observed that the outer or free marginal portion of the dial 6 is adapted to engage the inner periphery of the annular flange 9 vproduced on the outer face vof the cover 2 in concentric relation with the sleeve 3.

The knob 5 a'ords a nieanswhereby'the desired axial rotation may be imparted to the spindle fi by hand, although l have found in practice that under certain conditions and as illustrated in Fig. 8, the knob 5 may be omitted and the dial 6 be carried lby the spider 5a operatively engagedgwith the spindle and the dial provided with the radial extension l0, adapted to be engaged by a :toot which, in connection with motor vehicles, has proven to be olf especial benefit? Fixedly secured to the inner extremity of the spindle l is a disk 'li preferably of brass, while l2 denotes a plurality of disks also preferably of brass loosely mounted upon the spindle 4 and clainpingtherebetween the disks lli of liber or other nonconductive material, the requisite engagement between the disks l2 and le being maintained, as herein disclosed, through the ict cover 2, said washer beingA provided with spring tongues 17' serving in a manner and for a purpose' which is believed to. selfevident. Y i

The disks 14 serve as the tumblers for a permutation mechanism and are provided in their peripheries with the notches`18 adapted to be brought in requisite alinement by proper manipulation of the spindle 4, said disks 14 being provided with the laterally disposed pins 19 coacting in a manner which is believed to be self-evident.

The depth of the notches 18 are such as to' permit, when in alined relation, of Contact between the peripheries of the disks 14 and..v

the head 20 of the substantially U-sh-ape awl or lever 21 of conductive material. As herein embodied, the stems of the pawl or lever 21 are rotatably supported by the contact post 22, the head 20 ofthe pawl or lever 21 being normally maintained in engagement with the peripheries of the disks 14 under the influence of the spring 23 herein disclosed as a coil spring surrounding said contact post 22 and having one extremity anchored thereto while the opposite extremity of such spring is suitably connected with the pawl or lever 21.

As herein embodied, the contact post 22 is operatively supported by the, retaining member 16 and the annular member 24 of fiber or other non-conductive material.v The annular member 24 is provided with the oontact plates 25 provided with the binding posts 26 'whereby the desired electrical connection through the medium of the conductors o may be had with the battery and magneto. s The casing 1 is provided with suitable openings 27 through which the conductors c are directed. Coacting with the contact plates 25 is the brush 28 projecting from the lower extremity ofthe spindle 4 and maintained in operative position thereon through the vmedium. of the clamping nut 29, said plate 25 having the extensions 25n projecting inwardly of the member, 24 and with which the brush 28 engages.

The contact post, hereinbefore referred to, has its lower extremity in engagement withthe contact plate 30 provided with a binding post 31 whereby a connection may be had through the conductor c with the coil, said casing being provided with a suitable -opening 32 through which said conductor is directed. The member 24 is also pro,- vided with a plate 33 projecting inwardly of the member 24 and on which the brush 28 is adapted to rest when the spindle 4 is adjusted into of position.

adapted to coact with the pin of the adjacent disk 14 whereby it will be readily perceived thaty the tumblers aorded by the disks 14 are caused to properly operate, and

it will also be observed that the cam 34 serves, upon the axial rotation of the spindle4, to raise the head of the pawl or lever 21 from within the alined notches 18. j

It is to be observed thatfthe low point a of the cam 34 is of such an extent-as topermit an independent movement thereof under the influence of the spindle 4 in order that` the requisite engagement or contact may be had as required-with either of the contact plates 2,5. In order that it may be readily determined which of the lates 25the brush is in contact with or to. etermine its position upon the late 33, the demarcations,

hereinbefore re erred to, have positioned in close proximity thereto'suitable identities or indications 35.

When the pawl or lever 21 is adjusted from -within the notches 18, the head 20 is caused to engage an inwardly disposed projection 36- carried by the inner wall of the casing 1 whereby it will be readily perceived that the cover member 2 is effectively held against movement which would result in its disengagement or separation from the casing. By this arrangement, it will be readily perceived that access" within the casing 1 by unauthorized persons is eifectually guarded against.

In orderlto afford a positive stop dial 6 when thesame has been properly adjusted relative to the plates 25, which adjustment is determined by the arrow "37, I find it of advantage to produce in the dial 6, suitable recesses or openings 38 in which is adapted tobe automatically projected the spring pressed locking member 39 carried by the cover member 2 and operating' in a manner which is believed to beself-evident. It is also thought to be obvious that when it is necessary to adjust the dial 6 in order to properiy set the disks 14 and the cam 34, the member 38 is adjusted away from the dial. y. f

From the foregoing deseriptiomit is thought to be obvious that a circuit. closer constructed in 'accordance with invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may he 'assembled, and it will also be obvious that my invention is susceptible of some change and modication without material departure from the principles and spirit'thereof' and for this reason I do f not wish to be.

for the n eral parts herein shown in'carrying. out my invention in practice.

I claim:

1. A circuit closer comprising a casing, a plurality of contacts mounted therein, a spindle projecting within the casing and adapted to engage certain of the contacts, and a permutation mechanism within the casing under`.control of the spindle, said mechanism includingv a movable member electrically connected with a second contact and adapted to electrically engage the spindle upon a lpredetermined adjustment Iof the permutation mechanism.
